(First embodiment)
(Constitution)
FIG. 1 is a configuration diagram showing a device configuration of an endoscope system according to the present embodiment.

The endoscope system 1 includes an endoscope apparatus 2, another endoscope apparatus 3 as an observation instrument, and a control device 4. That is, in the present embodiment, the endoscope system 1 includes two endoscope apparatuses 2 and 3.
The endoscope device 2 includes an endoscope 11, a video processor 12, a light source device 13, and a monitor 14.

  The endoscope 11 has an insertion portion 11a to be inserted into a subject, and an operation portion 11b connected to the proximal end of the insertion portion 11a. The universal cable 11c extending from the operation portion 11b is used to connect the video processor 12 to the video processor 12. It is connected to the light source device 13. The endoscope 11 is an observation instrument for observing the inside of a subject.

The video processor 12 is also electrically connected to the light source device 13 and the monitor 14.
The insertion portion 11a has an observation window 2a and an illumination window 2b (FIG. 2) at the tip. Illumination light from the light source device 13 is light that is discontinuously emitted by periodically repeating an on state (emission state) and an off state (non-emission state), and is a light that is inserted through the insertion portion 11a. The light is emitted from the illumination window 2b to the observation target region through a guide (not shown). That is, the illumination window 2b constitutes an illumination unit that emits illumination light that illuminates the subject.

  An imaging element (not shown) that receives the reflected light that has passed through the observation window 2 a serving as an observation unit generates an imaging signal and outputs it to the video processor 12. The video processor 12 generates an image (an endoscope image that is a first image) by the image generation unit 33 (FIG. 2) based on the imaging signal, and outputs the image signal to the monitor 14.

Therefore, the surgeon can view an image (endoscopic image) in the subject using the endoscope 11.
Similarly, the endoscope apparatus 3 includes an endoscope 21 as an observation instrument, a video processor 22, a light source device 23, and a monitor 24.

  The endoscope 21 has an insertion portion 21a to be inserted into a subject and an operation portion 21b connected to the proximal end of the insertion portion 21a. A universal cable 21c extending from the operation portion 21b allows the video processor 22 to The light source device 23 is connected. The endoscope 21 is an observation instrument for observing the inside of a subject.

The video processor 22 is also electrically connected to the light source device 23 and the monitor 24.
The insertion part 21a has an observation window 3a and an illumination window 3b (FIG. 2) at the tip. The illumination light from the light source device 23 is light that is discontinuously emitted by periodically repeating the on state (emission state) and the off state (non-emission state), and is a light inserted through the insertion portion 21a. The light is emitted from the illumination window 3b to the observation target region through a guide (not shown). That is, the illumination window 3b constitutes an illumination unit that emits illumination light that illuminates the subject.

An imaging device (not shown) that receives the reflected light that has passed through the observation window 3 a serving as an observation unit generates an imaging signal and outputs the imaging signal to the video processor 22. The video processor 22 generates an image (an endoscopic image that is a second image) by the image generation unit 43 (FIG. 2) based on the imaging signal, and outputs the image signal to the monitor 24.
Therefore, the surgeon can view an image (endoscopic image) in the subject using the endoscope 21.

  The control device 4 is an endoscope system control device that is electrically connected to the video processor 12, the light source device 13, the video processor 22, and the light source device 23 through signal cables L1, L2, L3, and L4, respectively.

  The control device 4 controls image acquisition in the video processors 12 and 22 based on the emission state of the illumination light of the light source devices 13 and 23.

  Here, the two endoscope apparatuses 2 and 3 have the monitors 14 and 24, respectively. However, the output images from the two video processors 12 and 22 are synthesized and displayed on the display screen of one monitor. Alternatively, they may be displayed side by side or like a picture-in-picture.

FIG. 2 is a block diagram of the endoscope system.
As shown in FIG. 2, the endoscope 11 has an observation window 2a and an illumination window 2b at the distal end portion of the insertion portion 11a. The endoscope 11 includes an imaging unit 31 that receives light from a subject received through the observation window 2a and generates an imaging signal. That is, the imaging unit 31 images the inside of the subject and outputs an imaging signal. The imaging period of the imaging unit 31 is equal to or shorter than the continuous emission period when the light emitting unit 35 is in the emission state, and is preferably shorter than the continuous emission period when the light emitting unit 35 is in the emission state. Therefore, in this case, the imaging unit 31 images the subject at an interval (TC1) shorter than the continuous emission period of the illumination light of the light emitting unit 35. The illumination window 2b emits illumination light IL1 from the light source device 13.

The video processor 12 includes a control unit 32, an image generation unit 33, and a buffer circuit 34.
The control unit 32 includes a central processing unit (hereinafter referred to as CPU), ROM, RAM, timing generator, and the like, and controls the operation of the image generation unit 33 and also controls the operation of the light source device 13.
The control unit 32 outputs an image generation control signal CS1 that causes the image generation unit 33 to generate an image (an endoscope image that is a first image) based on the imaging signal from the imaging unit 31 of the endoscope 11. . The control unit 32 outputs a light emission control signal CS11 that instructs the light source device 13 to output illumination light. When the light emission control signal CS11 is received, the light source device 13 emits illumination light at a predetermined interval.

An image signal of an image (endoscopic image) generated by the image generation unit 33 is stored in a buffer circuit (hereinafter referred to as a buffer) 34 and then supplied to the monitor 14 as a video signal.
The light source device 13 includes a light emitting unit 35 and a light emission control unit 36. The light emitting unit 35 includes a light emitting element such as an LED.
Here, the light emitting unit 35 uses a light emitting element such as an LED, but may be a so-called frame-sequential light source having a lamp that emits white light and an RGB rotary filter.

  The light emission control unit 36 performs drive control of the light emitting unit 35 such that the illumination light is emitted from the light emitting unit 35 repeatedly and repeatedly in the emission state and the non-emission state. That is, the light source device 13 operates to alternately switch between an on state in which the illumination light is emitted and an off state in which the illumination light is not emitted.

  When the control device 4 is not connected, the control unit 32 outputs the image generation control signal CS1 to the image generation unit 33 at the same timing as the light emission timing of the light emission control signal CS11. An image of the subject (endoscopic image) when light is emitted and the subject is illuminated is generated.

  Further, the control unit 32 outputs the image generation control signal CS1 at the light emission timing by the light emission control signal CS11 when the control device 4 is connected or when the control device 4 is connected and in the single operation mode. The timing is changed so that the image generation control signal CS1 is output according to the timing control signal IP1 from the control device 4 without outputting to the generation unit 33.

  The light source device 13 is alternately switched between the on state and the off state described above. When the control device 4 is connected, the light source device 13 outputs a light emission state signal IS1 indicating the on state or the off state to the control device 4.

  Similarly, the endoscope 21 has an observation window 3a and an illumination window 3b at the distal end portion of the insertion portion 21a. The endoscope 21 includes an imaging unit 41 that receives light from a subject received through the observation window 3a and generates an imaging signal. That is, the imaging unit 41 images the inside of the subject and outputs an imaging signal. The imaging period of the imaging unit 41 is shorter than the continuous emission period when the light emitting unit 45 is in the emission state. Therefore, the imaging unit 41 images the subject at an interval (TC2) shorter than the continuous emission period of the illumination light of the light emitting unit 45. The illumination window 3b emits illumination light IL2 from the light source device 23.

The video processor 22 includes a control unit 42, an image generation unit 43, and a buffer circuit 44.
The control unit 42 includes a CPU, a ROM, a RAM, a timing generator, and the like, and controls the operation of the image generation unit 43 and also controls the operation of the light source device 23.
The control unit 42 outputs an image generation control signal CS2 that causes the image generation unit 43 to generate an image (an endoscope image that is a second image) based on the imaging signal from the imaging unit 41 of the endoscope 21. . The control unit 42 outputs a light emission control signal CS21 that instructs the light source device 23 to output illumination light. When receiving the light emission control signal CS21, the light source device 23 emits illumination light at a predetermined interval.

  The emission interval of the illumination light from the light source device 13 and the emission interval of the illumination light from the light source device 23 are set separately and are not synchronized with each other. Therefore, the illumination light of the light source device 13 and the illumination light of the light source device 23 are emitted at a certain moment, both are not emitted, or only one of the two illumination lights. May be emitted. Therefore, the illumination windows 2b and 3b periodically repeat the emission state and the non-emission state at a timing including a state in which the illumination light of the light source device 13 and the illumination light of the light source device 23 are emitted exclusively from each other. Exit.

Here, the emission timing of the illumination light of each of the light source devices 13 and 23 is controlled by the respective light emission control units, but the control device 4 may be provided with a light emission control unit.
The image signal of the image (endoscopic image) generated by the image generation unit 43 is stored in the buffer 44 and then supplied to the monitor 24 as a video signal.

The light source device 23 includes a light emitting unit 45 and a light emission control unit 46. The light emitting unit 45 includes a light emitting element such as an LED.
Here, although the light emitting unit 45 uses a light emitting element such as an LED, a so-called frame sequential light source having a lamp that emits white light and an RGB rotary filter may be used.

  The light emission control unit 46 performs drive control of the light emitting unit 45 so that the illumination light is emitted from the light emitting unit 45 in a periodically repeated state of emission and non-emission. That is, the light source device 23 operates to alternately switch between an on state in which the illumination light is emitted and an off state in which the illumination light is not emitted.

  The control unit 42 outputs the image generation control signal CS2 at the same timing as the light emission timing of the light emission control signal CS21 when the control device 4 is not connected or when the control device 4 is connected and in the single operation mode. By outputting to the image generation unit 43, the image generation unit 43 generates an image (endoscopic image) of the subject when the illumination light is emitted and the subject is illuminated.

  Further, when the control device 4 is connected, the control unit 42 does not output the image generation control signal CS2 to the image generation unit 43 at the light emission timing by the light emission control signal CS21, and the timing control signal IP2 from the control device 4 is output. The timing is changed so as to output the image generation control signal CS1.

  The light source device 23 is alternately switched between the on state and the off state described above. When the control device 4 is connected, the light source device 23 outputs a light emission state signal IS2 indicating the on state or the off state to the control device 4.

  The control device 4 includes a CPU 51, a memory 52 such as a ROM and a RAM, and an input / output interface (I / F) 53. The memory 52 stores an operation control program which will be described later, and the CPU 51 reads and executes the operation control program. The operation control program is a program for controlling operations of the video processors 12 and 13 and the light source devices 13 and 23. The input / output interface 53 is a circuit for transmitting and receiving various signals to and from the video processors 12 and 22 and the light source devices 13 and 23.

  Since the control device 4 is connected to the video processor 12, the light source device 13, the video processor 22, and the light source device 23 by signal cables L1, L2, L3, and L4, respectively, the connection state of each device that is powered on is determined. Can be determined.

The control device 4 acquires the light emission state signals IS1 and IS2 indicating the illumination light emission states of the light source devices 13 and 23, and acquires images in the video processors 12 and 22 based on the acquired light emission state signals IS1 and IS2. Timing control signals IP1 and IP2 are output.
(Operation)
Next, the operation of the control device 4 will be described.

FIG. 3 is a flowchart showing an example of the flow of processing of the operation control program in the control device.
When the power of the control device 4 is turned on, the CPU 51 executes processing based on the operation control program stored in the memory 52 shown in FIG.

  The control device 4 determines whether or not the video processor 12 as the first video processor is connected (step (hereinafter abbreviated as S) 1). Whether or not the video processor 12 is connected (or whether or not the video processor 12 is powered on) is determined based on the presence or absence of a signal from the video processor 12 via the signal cable L1.

  When the video processor 12 is not connected (S1: NO), the control device 4 determines whether or not the video processor 22 as the second video processor is connected (S2). Whether or not the video processor 22 is connected (or whether or not the video processor 22 is powered on) is determined based on the presence or absence of a signal from the video processor 22 via the signal cable L3.

When the video processor 22 is not connected (S2: NO), the process returns to S1, and the control device 4 does nothing.
In S2, when the video processor 22 is connected (S2: YES), the control device 4 turns on the light source device 23, which is the second light source device, and instructs the video processor 22 to acquire an image (S3).

  In response to the instruction in S3, the light emission control unit 46 performs drive control of the light emitting unit 45 so that illumination light is periodically emitted from the light emitting unit 45, and the control unit 42 generates an image at the light emission timing by the light emission control signal CS21. By outputting the control signal CS2, the image generation unit 43 generates an image (endoscope image) of the subject when the illumination light is emitted and the subject is illuminated.

That is, the endoscope apparatus 3 enters the single operation mode state according to the instruction of S3.
When the video processor 12 is connected (S1: YES), the control device 4 determines whether or not the video processor 22 as the second video processor is connected (S4).

  When the video processor 22 is not connected (S4: NO), the control device 4 turns on the light source device 13, which is the first light source device, and instructs the video processor 12 to acquire an image (S5).

  In response to the instruction of S5, the light emission control unit 36 performs drive control of the light emitting unit 35 so that illumination light is periodically emitted from the light emitting unit 35, and the control unit 32 generates an image at the light emission timing by the light emission control signal CS11. By outputting the control signal CS1, the image generation unit 33 generates an image (endoscope image) of the subject when the illumination light is emitted and the subject is illuminated.

That is, the endoscope apparatus 2 enters the single operation mode state according to the instruction of S5.
When the video processor 22 is connected (S4: YES), the control device 4 turns on the light source device 13 that is the first light source device and the light source device 23 that is the second light source device (S6).

The control device 4 determines whether or not the light source device 13 that is the first illumination device is in a light emitting state (S7). This determination is made based on the light emission state signal IS1 from the light emission controller 36.
When the first lighting device is not in the light emitting state (S7: NO), the control device 4 determines whether or not the light source device 23 that is the second lighting device is in the light emitting state (S8). This determination is made based on the light emission state signal IS2 from the light emission control unit 46.

When the second lighting device is not in the light emitting state (S8: NO), the control device 4 does not perform any processing and returns to the processing in S7.
When the first lighting device is in the light emitting state (S7: YES), the control device 4 determines whether or not the light source device 23, which is the second lighting device, is turned off (S9). This determination is also made based on the light emission state signal IS2 from the light emission controller 46.

When the light source device 23 that is the second illumination device is not turned off (S9: NO), the control device 4 does not perform any processing and returns to the processing of S7.
The two light source devices 13 and 23 emit the illumination light so as to periodically repeat the emission state and the non-emission state without being related to each other, but in the case of NO in S9, both the two light source devices 13 and 23 are Since the illumination light is emitted, when the two video processors 12 and 22 acquire images and generate two images (endoscopic images), the bright spot of the other party's illumination light is displayed on both images (internal view). (Mirror image).

  When the light source device 23 that is the second illumination device is in an extinguished state (S9: YES), the control device 4 instructs the video processor 12 that is the first video processor to acquire an image (S10). Specifically, the control device 4 outputs a timing control signal IP1 to the control unit 32.

  When YES in S9, since only the light source device 13 emits light, the bright spot due to the illumination light of the light source device 23 of the endoscope device 3 appears in the image (endoscopic image) generated in the video processor 12. There is no reflection.

FIG. 4 is a timing chart for explaining the illumination period and imaging timing of each light source device.
The light emission state signal IS1 indicates the timing at which the light emitting unit 35 emits light. The light emission state signal IS2 indicates the timing at which the light emitting unit 45 emits light.

  In FIG. 4, for example, during a period T1 from time t1 to time t2, illumination light from both the light source device 13 and the light source device 23 is applied to the subject. For example, during a period T2 from time t2 to t3, the subject is irradiated with illumination light from only the light source device 13. For example, during the period T3 from time t3 to t4, the illumination light from either the light source device 13 or the light source device 23 is not irradiated on the subject. For example, during a period T4 from time t4 to t5, the subject is irradiated with illumination light from only the light source device 23.

  The imaging cycle TC1 of the imaging unit 31 is shorter than the ON period (for example, the period from t1 to t3) of the light emitting unit 35. Therefore, the imaging unit 31 generates imaging signals of a plurality of frames within the on period of the light emitting unit 35.

  Similarly, the imaging cycle TC2 of the imaging unit 41 is also shorter than the ON period (for example, the period from t4 to t6) of the light emitting unit 45. Therefore, the imaging unit 41 generates an imaging signal of a plurality of frames within the ON period of the light emitting unit 45.

Therefore, for example, when S9 is NO, it is a timing within the period T1, and when S9 is YES, it is a timing within the period T2.
When YES in S8, the control device 4 instructs the video processor 22 that is the second video processor to acquire an image (S11). Specifically, the control device 4 outputs a timing control signal IP2 to the control unit 42.

Thus, for example, when S8 is NO, it is a timing within the period T3, and when S8 is YES, it is a timing within the period T4.
After S10 and S11, the control device 4 determines whether or not the power source of the control device 4 is turned off (S12). When the power of the control device 4 is not turned off (S12: NO), the process returns to S7. When the power of the control device 4 is turned off (S12: YES), the process ends.

  As described above, when NO in S9, for example, is a timing within the period T1, and when YES is determined in S9, for example, is a timing within the period T2. Moreover, when it becomes NO at S8, it is a timing within the period T3, for example, and when it becomes YES at S8, it is a timing within the period T4.

  Therefore, in the two endoscope apparatuses, only when the illumination light from one of the light source devices is emitted to the subject, the image generation unit of the video processor corresponding to the light source device of the control device 4 Only when the illumination light from the other light source device is emitted to the subject, the image generation unit of the video processor corresponding to the light source device acquires the imaging signal, so that it is displayed on the two monitors. The two images (endoscopic images) do not include bright spots or the like due to reflection of the illumination light of the other endoscope.

  That is, the control device 4 includes the first image (endoscopic image) based on the imaging signal output at the timing (for example, T2) when only the illumination light from the illumination window 2b is emitted, and the illumination window 3b. A display control unit for displaying the second image (endoscopic image) based on the imaging signal output at the timing when only the illumination light is emitted (for example, T4) on the monitors 14 and 24 which are display devices, respectively; Configure. More specifically, the control device 4 serving as a display control unit captures images of the imaging unit 31 at a timing (for example, T2) when the illumination window 2b emits illumination light and the illumination window 3b does not emit illumination light. The first image is obtained by acquiring a signal, acquiring the imaging signal of the imaging unit 41 at a timing (for example, T4) when the illumination window 3b emits illumination light and the illumination window 2b does not emit illumination light. The display of the (endoscopic image) and the second image (endoscopic image) is controlled.

FIG. 5 is a diagram for explaining endoscopic mucosal resection (EMR) in which a polyp formed in the stomach is excised using two endoscopes.
A hole is made in the body wall 61 of the patient P and the stomach wall 62a of the stomach 62, and the trocar 63 is set in the hole. A balloon 63 a is provided at the tip of the trocar 63. The trocar 63 is fixed to the patient P by a stopper 64 provided outside the body wall 61. The insertion portion 11 a of the first endoscope 11 is inserted into the stomach 62 through the trocar 63.

Further, the insertion portion 21a of the second endoscope 21 is inserted from the mouth of the patient P.
The two endoscopes 11 and 21 are operated by two operators.
The operator who operates the endoscope 11 can see the lesion LS by bringing the distal end of the insertion portion 11a closer to the lesion LS. Similarly, the operator who operates the endoscope 21 can see the lesion LS by bringing the distal end portion of the insertion portion 21a closer to the lesion LS.

  An operator who operates the endoscope 11 inserts the forceps 65 from the treatment instrument insertion port 11d of the endoscope 11, and projects the distal end portion of the forceps 65 from the treatment instrument opening at the distal end of the insertion portion 11a. it can. Similarly, the operator who operates the endoscope 21 inserts the snare 66 from the treatment instrument insertion port 21d of the endoscope 21, and projects the distal end portion of the snare 66 from the treatment instrument opening at the distal end of the insertion portion 21a. Can be made.

  An operator who operates the endoscope 11 grasps the stomach wall 62a in the vicinity of the lesioned part LS with the forceps 65 while looking at the image (endoscopy image) displayed on the monitor 14, and the snare 66 of the lesioned part LS. The operation of lifting the stomach wall 62a is performed until it can be hung down.

  On the other hand, the operator who operates the endoscope 21 confirms that the metal ring of the snare 66 is hung under the lesion LS while viewing the image (endoscopic image) displayed on the monitor 24. Above, the metal ring is tightened, and a high frequency current is passed through the snare 66 to excise the lesioned part LS.

  Conventionally, since an image (endoscopic image) displayed on the monitor 14 has a bright spot by illumination light of the endoscope 21, the operator who operates the forceps 65 is difficult to view as an image. It was difficult to operate. In addition, since an image displayed on the monitor 24 (endoscopic image) includes a bright spot due to illumination light of the endoscope 11, the operator who operates the snare 66 is difficult to view as an endoscopic image. The snare 66 was difficult to operate.

  However, as described above, according to the above-described embodiment, the image (endoscopic image) displayed on the monitor 14 of the endoscope apparatus 2 includes a bright spot by illumination light of the endoscope apparatus 3 and the like. The image (endoscopic image) displayed on the monitor 24 of the endoscope apparatus 3 does not have a bright spot or the like due to the illumination light of the endoscope apparatus 2.

  As described above, according to the present embodiment described above, in a system using two endoscopes, a bright spot or the like is included so that no bright spot is generated by illumination light of the other endoscope. It is possible to provide an endoscope system and an endoscope system control apparatus that can obtain a clear image (endoscopic image) that is not necessary.

  As a result, in a system using two endoscope devices, clear images (endoscopic images) in which no bright spots are generated by illumination light of the other endoscope can be obtained. Inspection and treatment can be performed smoothly.

Further, the emission timing of the illumination light from the light source device 13 and the emission timing of the illumination light from the light source device 23 are set separately and do not need to be synchronized with each other.
(Modification 1)
In the above-described embodiment, the image generation control signals CS1 and CS2 are output in response to the timing control signals IP1 and IP2 from the control device 4, and the image acquisition in the video processors 12 and 22 is performed. 33 and 43 may acquire images continuously at predetermined timing intervals to generate images (endoscopic images) and store them in the buffers 34 and 44, respectively. In the first modification, only the images corresponding to the timing control signals IP1 and IP2 are output to the monitors 14 and 24 from the images of a plurality of frames stored in the buffers 34 and 44.

  In FIG. 2, only the image generated only when only one illumination light is emitted by supplying the timing control signals IP1 and IP2 to the buffers 34 and 44, respectively, as indicated by a two-dot chain line. May be displayed on the monitors 14 and 24.

That is, the imaging unit 31 images the subject when the illumination light is emitted from the illumination window 2 b, and a plurality of imaging signals are stored in the buffer 34. The imaging unit 31 images the subject when the illumination light is emitted from the illumination window 2 b, and the generated plurality of image signals are stored in the buffer 34. The first image (endoscopic image) at the timing when the illumination light is emitted only from the illumination window 2b among the plurality of images (endoscopic images) stored in the buffer 34 is the monitor 14. Is displayed. The imaging unit 41 images the subject when the illumination light is emitted from the illumination window 3 b, and the plurality of generated image signals are stored in the buffer 44. The second image (endoscopic image) at the timing when the illumination light is emitted only from the illumination window 3b among the plurality of images (endoscopic images) stored in the buffer 44 is the monitor 24. Is displayed.
(Modification 2)
In the above-described embodiment, the emission timings of the illumination light emitted from the two light source devices are irrelevant to each other. Since it may not be displayed on a monitor, the problem that it is hard to see as an image may arise. Therefore, the image signal output to the monitor may be held, and the held image signal may be output to the monitor.

In the case of the second modification, the memories 111 and 112 shown by dotted lines in FIG. 2 are provided on the image signal output lines to the monitors 14 and 24, respectively.
That is, when the first and second images (endoscopic images) are successively generated, the memories 111 and 112 serving as storage units generate the generated first endoscope image and the generated second endoscope. Images (endoscopic images) are stored. The generated first image (endoscopic image) and the generated second image (endoscopic image) recorded in the memories 111 and 112 are respectively the following first images (endoscope). The image is displayed on the monitors 14 and 24 until the image is generated and until the next second image (endoscopic image) is generated.

Since the image signals stored in the memories 111 and 112 are supplied to the monitors 14 and 24, respectively, the images (endoscopic images) displayed on the monitors 14 and 24 are displayed without interruption. It is hard to see for the person.

The mirror 81 can be fixed at either the first position or the second position by a control signal from the control device 4A.
The switching device 72 may be a device having another configuration.

  FIG. 8 is a configuration diagram of a switching device according to a modification. The switching device 72A has a light shielding plate 91 disposed between the distal end portion of the light guide 73 and the proximal end portions of the two light guides in the universal cables 11c and 21c.

  The light shielding plate 91 is a light shielding member that can move between two positions parallel to the plane of the support plate 92 and as indicated by an arrow A1. The light shielding plate 91 is movable between two positions by a driving element 91a having a coil, a piezoelectric element, etc. connected to the light shielding plate 91.

  The control device 4A determines whether or not the mirror 81 is at the first position (S2-7). This determination is made based on the presence or absence of the contact signal TS1 via the signal cable L6.

  When the mirror 81 is not in the first position (S2-7: NO), the control device 4A determines whether or not the mirror 81 is in the second position (S2-8). This determination is performed based on the presence or absence of the contact signal TS2 via the signal cable L6.

When the mirror 81 is not in the second position (S2-8: NO), the control device 4A does not perform any processing and returns to the processing in S2-7.
When the mirror 81 is in the first position (S2-7: YES), the control device 4A instructs the video processor 12, which is the first video processor, to acquire an image (S2-9). Specifically, the control device 4 outputs a timing control signal IP1 to the control unit 32.

  After S2-9 and S2-10, the control device 4A determines whether or not the power supply of the control device 4A is turned off (S2-11). When the power of the control device 4A is not turned off (S2-11: NO), the process returns to S2-7. When the power of the control device 4A is turned off (S2-11: YES), the process ends.
